动态添加控件：
protected void Button1_Click(object sender, EventArgs e)
{
int column = GridView1.HeaderRow.Cells.Count;//得到GridView1列的方法
for (int i = 0; i < column; i++)
{
string txtID = "New"+GridView1.HeaderRow.Cells[i].Text.ToString();
TextBox tmp = new TextBox();
tmp.ID = txtID;
Form.FindControl("TD2").Controls.Add(tmp);
}
}
获取其值：
protected void Button2_Click(object sender, EventArgs e)//递交
{
Hashtable ht = new Hashtable();
string table_name = Label1.Text;
string[] ak = Request.Form.AllKeys;
for (int i = 0; i < Request.Form.Count; i++)
{
//只筛选出动态生成的三个控件的值
if (ak[i].IndexOf("New") > -1)
{
string a = ak[i].Substring(3);
ht.Add(ak[i].Substring(3), SqlStringConstructor.GetQuotedString(Request.Form[i]));
}
}
db.Insert(table_name, ht);
Gridview_Find();
}
